Accurate risk stratification for patients with non-dilated left ventricular cardiomyopathy (NDLVC) remains challenging due to lack of dedicated clinical trials. This post-hoc analysis aims delineate the arrhythmic and assess incremental value cardiac magnetic resonance (CMR) imaging in DERIVATE (CarDiac MagnEtic Resonance Primary Prevention Implantable CardioVerter DebrillAtor ThErapy) study cohort meeting NDLVC diagnostic criteria. Patients from registry were identified absence (LV)...
The aim of this registry was to evaluate the additional prognostic value a composite cardiac magnetic resonance (CMR)-based risk score over standard-of-care (SOC) evaluation in large cohort consecutive unselected non-ischaemic cardiomyopathy (NICM) patients.In DERIVATE (www.clinicaltrials.gov/registration: RCT#NCT03352648), 1000 (derivation cohort) and 508 (validation NICM patients with chronic heart failure (HF) left ventricular ejection fraction <50% were included. All-cause mortality...
Abstract Background and Aims Classification risk stratification in aortic (AR), mitral (MR), tricuspid regurgitation (TR) remains a significant clinical challenge. This study aimed to develop an artificial intelligence (AI) system assess valvular stratify MR progression risk. Methods Using transthoracic echocardiograms (TTEs) at two sites (internal development/test, external test), the DELINEATE-Regurgitation was developed classify AR, MR, TR severity using color Doppler videos. of summating...
Right ventricular systolic dysfunction (RVSD) is an important determinant of outcomes in heart failure (HF) cohorts. While the quantitative assessment RV function challenging using 2D-echocardiography, cardiac magnetic resonance (CMR) gold standard with its high spatial resolution and precise anatomical definition. We sought to investigate prognostic value CMR-derived a large cohort HF reduced ejection fraction (HFrEF).Study comprised patients enrolled CarDiac MagnEtic Resonance for Primary...
Mitral annular calcification (MAC) negatively influences outcomes in surgical mitral valve (MV) repair for regurgitation (MR). However, there are no data on whether MAC impacts of MitraClip percutaneous MV edge-to-edge repair. This study sought to investigate the presence procedural success and durability transcatheter MR using MitraClip.One hundred seventy-three patients undergoing significant were studied. Patients with moderate-or-severe (n=28) compared those no-or-mild MAC....
Introduction: Recent studies using deep learning techniques have demonstrated promising left ventricular ejection fraction (LVEF) assessment from transthoracic echocardiograms (TTEs). However, most prior focused on videos a single apical view, technique known to be subject limitations given the regionality of LV systolic function. We hypothesized that model trained include echocardiographic video clips multiple views large dataset will improve accuracy in LVEF assessment. Methods: identified...
Introduction: Mitral annular calcification (MAC) has been associated with age, hemodialysis (HD) status, coronary disease, and mortality. While MAC is seen frequently in pts undergoing percutaneous edge-to-edge repair of mitral regurgitation (MR) its impact on survival unknown. Hypothesis: not mortality after MR repair. Methods: Pts who underwent MitraClip between Apr 2009 May 2014 were included. Kaplan-Meier was plotted no MAC. A multivariate Cox regression all-cause performed...
Abstract Funding Acknowledgements Type of funding sources: None. Background Current guidelines advocate for a multi-parametric approach to echocardiographic quantitation tricuspid regurgitation (TR). The primary quantitative measure TR severity uses the proximal isovelocity surface area (PISA) method calculate effective regurgitant orifice (EROA) and volume (RegVol). However, EROA-PISA may underestimate due low flow tethering leaflets. Purpose purpose this study was compare standard...
Background: Quantitative volumetric assessment of the right ventricle (RV) can significantly enhance risk stratification in heart failure (HF), especially with increasing availability cardiac MRI (CMR). The prognostic value RV dilation measured by end diastolic volume indexed to body surface area (RVEDVi) is not yet well established. In this analysis, we investigate significance RVEDVi CMR a stable HF cohort. Methods: We conducted retrospective analysis on DERIVATE registry, large cohort...
